0 Introduction
In 2010, the "green", "low carbon" has become one of two hot topics, especially the recent frequency of major geological disasters, extreme weather, the life of our people and property caused incalculable damage, we increasingly changes in the weather felt more terrible disaster to mankind, so let the whole community has been pressing the state into a low-carbon life.

Colleges and universities as disseminators of human civilization and the creators should bear the lead of human civilization, to enhance public awareness of the task, both their own Development needs, it is given a social duty. Colleges and universities to become a good "low-carbon economy "the vanguard of efforts to build a conservation-campus at my school construction plan Jiangning the occasion of the Western campus, proposed to build" low carbon campus' goal of building a harmonious, saving the beautiful campus.

A concept of low-carbon and low-carbon economy
Carbon, English as a low carbon. Means a lower or less greenhouse gases (mainly carbon dioxide emissions.

UK Government energy white paper <<Our energy future: creating a low carbon economy>> the first official pointed out that low-carbon economy, through less consumption of natural resources and less pollution, more Economic output , while creating higher standards of living and better quality of life means and opportunities for Development, deployment and export of advanced technology to create opportunities, but also create new business opportunities and more jobs.

Recently, many scholars have made the definition of low-carbon economy, low carbon economy [1], refers to the guidance of the concept of sustainable Development, through technical innovation, system innovation, industrial restructuring, new energy Development and other means, as far as possible coal, oil and other carbon reducing energy consumption, reduce greenhouse gas emissions, to achieve Economic and social Development and ecological environment protection as a win-win Economic development patterns.

[2] pointed out that low-carbon economy is the Economic development of carbon emissions, environmental and socio-Economic cost of the lowest economic cost, is a way to improve the ability of Earth's ecosystems, the sustainability of a strong self-regulation of the economy.

Low-carbon economy is a green economy is the low-carbon industries, low-carbon technologies, development of low-carbon economy and low-carbon life forms in general, low-carbon economy is to raise the real efficient use of energy, clean implementation of regional development and promote products low-carbon development and maintenance of the ecological balance of global low-carbon economy is the core of energy technology innovation and system innovation, without affecting the economic and social development context, through technical innovation and system innovation, can be as much as possible to maximize the reduction of greenhouse gas emissions to slow global climate change, achieve economic and social development of clean and sustainable development [3-5].

Low-carbon economy has changed the way the world economic growth, change our way of life, to some extent, the development of low-carbon economy will be a profound economic and social change. Today, the "low carbon" has been gradually accepted as a social trend.

2 Campus planning and construction of China's problems [6-7]
2.1 blind comparisons between colleges and universities, over the landscape construction - a large lake, large lawn, fountain, trees and other types of
Some colleges and universities interested in building large square (an area of ​​several acres), construction of large musical fountain, do not focus on land use efficiency and economic rationality of investment, waste a lot of school funding and social resources.

University campus environment in the planning tends to form large squares, highlighted the phenomenon of long axis of the campus is a large spatial scale, lack of intimacy, the road is too great, low building density, resulting in waste of land resources, too many of the pavilions , rockery fountain, rare trees, not the economy, does not apply, but university teachers and students need real-life sports facilities, equipment and activities, and can form the shade of the fast-growing species is rare.

Construction of school buildings blind 2.2, so that loss of culture
University environment should have its own characteristics and cultural heritage, which requires comprehensive planning, but the environment is often part of university press "in charge" of preferences, so that loss of the original features of the campus, and some blind imitation, or even increase the cost waste of resources to improve the campus environment but without any practical significance.

2.3 environment, "emphasis on the transformation of light to protect"
Some colleges and universities during campus environment, the surrounding environment of the base and often do not pay attention to protect the natural environment, the pursuit of ornamental and economic value to natural forests into plantations. This is entirely forest for the trees, the Department of Architecture, Southeast University, Professor Wang Jianguo stressed in the planning and design should firmly establish the concept of ecological and environmental priorities, the campus is not absolute, the more base level, the better to treat the base of the vegetation does not pay attention to the many foreign university campuses are clean and maintain the original natural landscape and ecological imprint, the formation of specific environmental features.

Indeed, this not only protect the environment, ecology, and conservation of social resources, is conducive to the sustainable development of the school.

2.4 waste of energy, the lighting is too bright, too cold air conditioning, heating temperature is too high
In offices, classrooms, libraries, etc., we often see in winter windows and doors fully open and the air conditioning temperature setting is high, need to add into the room in summer coat, or in the case of winter heating the open air while the temperature adjustment is very high, often people will be left to do with air-conditioning occurred, to do with fans, the phenomenon does not turn off the lights, too bright lighting, landscape lighting are all over the phenomenon of excessive energy waste.

3 introduces the concept of building a low carbon economy the need for new campus construction
Rapid economic development in today's society, excessive carbon dioxide emissions caused by a series of increasingly prominent, reduce carbon emissions by the community's close attention.

Universities should be the advocate and the development of "low-carbon economy," the pioneer, the universities should adopt advanced technology, strict and scientific management methods, so that the sustainable development of campus planning, campus planning and construction solutions based on the problems faced by colleges and universities on the need to campus planning to introduce the concept of low-carbon economy.

At present, countries have started implementing the low carbon university campus building in the United States, the university established the "Alliance president addressing climate change agreement", "environmental improvement committee", "Higher Education Commission on Sustainable Development" and other institutions, committed to reducing greenhouse gas emissions, protection of the natural environment, water conservation, material recycling, etc. on the campus of Yale University, Building 90 (a total of 300 school heating, ventilation and air-conditioning system has been modified, the use of automatic control, building installations across the thermal windows, make use of solar and wind energy at Harvard University, the implementation of a campus energy plan, resource efficiency program, the students planned and integrated green living and a series of low-carbon energy management program and achieved remarkable success on campus. In addition, the University of Nottingham Jubilee Campus Korea Campus is a new low-carbon example of campus construction, ecological building is recognized as one of the signs, designed to highlight the characteristics of eco-design, industrial land in the waste, based on the update to build into a park full of natural vitality style campus.

"Low-carbon economy" is emerging as a world development. China is the world's carbon emissions, one of the big, low-carbon economy will become China's economic development in the longer term the important themes of the strategic development of new China important part of the industry. domestic colleges and universities should actively respond to the campus planning and construction, should take the initiative to introduce the "low-carbon economy", and strive to build a conservation-campus, in the university campus to "low carbon" everywhere. turn affixed to the free download http://www.hi138.com 4 carbon construction of campus planning initiatives
On campus, especially in the new campus plan, put forward the guiding ideology of ecological principles to optimize the integration of each system, at all levels of low-carbon eco-technology, and finally to achieve a low carbon and sustainable development of low carbon campus.

In general, campus planning should consider the following aspects [8-10]:
4.1 the construction of the campus environment, ecological priority
Comprehensive understanding of the planning area of ​​natural resources, ecological environment and ecological characteristics and campus activities, contact the ecosystem as a whole to optimize the use of methods and principles, rational design and construction of school buildings, the pursuit of optimization of the campus as a whole and the overall harmony of the relationship, emphasizing the all departments and levels of coordination between the campus resources to maximize savings, use, school office, teaching, life and other buildings and the local environment combine to form an organic whole. The entire system has a self-regulatory capacity and anti-jamming capability, to achieve the sustainable development of the school.

4.2 to achieve the digital campus
At the same time can not be independent of the campus community, is a microcosm of society, so the campus planning and development should be based on local economic and resource conditions, the formation of campus culture and the surrounding socio-economic, ecological complementarity, efficient allocation of resources and utilization, coordinated development .

On campus construction, should pay attention to weak construction, the use of networks to strengthen the campus and community ties, so the campus Internet-based, in time and space to be extended, to achieve and social information sharing, and ultimately digital teaching, digital resources management .

4.3 Architectural design, implement conservation-oriented campus
Building a low carbon campus, of course, inseparable from carbon building low-carbon construction means construction materials and equipment manufacturing, construction, construction and building use throughout the life cycle, reduce fossil energy use, energy efficiency and reduce carbon dioxide emissions .

Low carbon content and energy-saving building construction, green building is consistent and complementary. Schools green campus of low-carbon development in the heating, cooling, electricity and other aspects of energy use to consider solar, geothermal and other renewable energy sources, the campus Try to use light sources used in building energy-saving lamps, LED and other low energy products, some building lighting technology the light pipe can be used to meet the requirements of the building for natural lighting, the building roof, the wall around the planting of vegetation outside the window, and the surrounding integration of the ecological environment, reduce the intrusion of nature,
4.4 raise awareness of teachers and students of low-carbon
Schools are required to take advanced, rigorous, scientific management methods, school teachers and students together to do water and energy conservation, waste disposal, sewage disposal, we work hand in hand, I start, start now, from around little things, conserve energy in school and gradually formed a glorious waste of energy shameful atmosphere.

5 Conclusion
Campus planning to introduce the concept of low-carbon, especially in the new campus construction, rational planning and design, implementation arrangements, building a low carbon campus, leading the community for the school to make its own contribution to low carbon campus.
